take a look at the KB https://support.emc.com/kb/88844 there you'll find a lot of performance troubleshooting tips and commands, also the definition you've asked for.
If you have some general question about performance metrics, I would recommend the free EMC² Education course Storage Performance Fundamentals (MR-1WP-STORPERFD).
